My Tesla App is not connecting to both my Powerwall and my Model S. It has been out since at least yesterday although there was a screen message 'last updated 26 December' That message has just changed to 'Yesterday' My wifi and internet connections are good. I can interrogate the Gateway IP address and my PVOutput is logging real time. TeslaFi shows last nights charge of Model S, but I can't control the car functions by the App. It says I am logged in. Is there a problem with the Tesla site? I am in UK
